Hotmelt pill is described in detail below.
In various embodiments, film-forming polymer compositions, which are formed, substantially completely covers the basic of hotmelt core Upper continuous film.This can be by being heated above its fusion temperature, then with molten by the film-forming composition for application State applies the film-forming composition to realize.It is preferred that applied by being coextruded.Two kinds of materials of shell and core are preferably compatible, So that they form stabilization, uniform mixture in fusing.In one embodiment of the invention, fusing point of shell material etc. In or less than nuclear material fusing point.
Film-forming polymer compositions defined above form coating or film, and the coating or film are at 20 DEG C to being no more than It is preferably inviscid at a temperature of 60 DEG C and protects adhesive core not affected by environment.Apply with pill shape according to this hair During bright hotmelt, hotmelt is melting, obtains the homogeneous mixture of shell material and nuclear material.Can be with By mixing apparatus, such as either statically or dynamically blender, or this method is accelerated by pump.Obtained melt is uniform Contact adhesive, and with the liquid form use/application.
The thickness of polymer film is typically 2-200 μm, particularly 10-100 μm, very particularly preferably about 20 μm.But Film thickness also depends on the size of pill.Therefore, in the hotmelt of pill shape, the gross weight based on hotmelt pill Amount, the amount of polymer film are typically not greater than 12 weight %, preferably 1-10 weight %, more preferably 3-8 weight %, particularly preferred 5- 7 weight %.
As described above, it is preferred to prepare the hotmelt of the pill shape of the present invention by being coextruded.In coextrusion method In, hotmelt or its component are melted and homogenized in mixing apparatus, is then extruded by extruder outlet or nozzle. Nozzle can have any conventional shape, but typically have slit shape or circular open, and composition is pumped via the opening. The temperature for generally remaining extruder nozzle is higher than the fusing point of material, and the temperature of extruder nozzle is usually 80-150 DEG C.In co-extrusion During going out, from extruder nozzle while film extrusion polymer composition, in particular so that film-forming polymer compositions conduct Continuous film substantially covers core to be covered, therefore substantially encapsulates hotmelt.This coextrusion method used herein It is well known in the prior art with equipment.
In a preferred embodiment, pill is formed in cooling water to enter by using nip rolls (nip roller) Prepared by row, wherein coextrusion hotmelt and polymer film.Then single pill is separated from each other in centrifugal dryer.This It is method known to those skilled in the art.
After cooling, pill packaging can be transported in container, box or bag.Container can be by mechanically stable Material is made, so as to transport and handle substantial amounts of pill.
Pill is preferably inviscid at a temperature of 20 DEG C to 60 DEG C, therefore can store and transport without being bonded in Together.
Hotmelt pill as described herein is particularly suitable as contact adhesive (contact adhesive (PSAs)) And for the purpose.Application field is, for example, such as when preparing amenities (particularly diaper), film is bonded to one another or Person bonds film and other substrates (such as textile cloth or non-woven fabrics).Therefore, the production bonded using the hotmelt of the present invention Product are equally the parts of the present invention.
When using the hotmelt pill of the present invention, typically they are placed in very big container, first They are provided in conveying equipment by step, and then, conveying equipment transports pill into melting unit.The conveying equipment can be Conveying worm or ribbon conveyer etc.；However, it is preferred to by air-flow, such as compressed air or negative pressure (vacuum) transport ball Grain.Because this conveying causes the mechanical friction between particle surface, therefore, coating is also prevented from gluing in conveying equipment herein Knot and aggegation.Therefore, the invention further relates to the method that hotmelt is supplied to melting unit, it includes passing through conveying equipment, Especially by vacuum conveying apparatus multiple hotmelt pills are provided to melting unit.Melted in pill in melting unit Afterwards, then melt is transported, is typically pumped to suitable distributing equipment, such as spray nozzle or roller, is set via distribution It is standby to apply pill to the substrate for it is expected bonding.
Can be in automated process by heat of the hotmelt pill described herein for applying hotmelt pill Melt adhesive.
Because pill can have smaller volume, therefore they allow the progress for example in conveying equipment simple, fixed To distribution.Therefore, the amount for the adhesive being present in melting unit can be reduced simultaneously, so as to avoid being melted in melting unit Change long time, excessive dosage or retention time length, this can cause adhesive component to be degraded.
Following examples are used to explain the present invention；But the invention is not restricted to this.
